Earnings Per Share [Abstract]  
EARNINGS PER SHARE
EARNINGS PER SHARE
The Company follows ASC 260, Earnings Per Share, in calculating earnings per share. Basic earnings per share is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding during the period. The holders of unvested restricted stock awards do not have nonforfeitable rights to dividends or dividend equivalents and therefore, such unvested awards do not qualify as participating securities and are excluded from the basic earnings per share calculation. Diluted earnings per share includes the determinants of basic net income per share and, in addition, gives effect to the potential dilution that would occur if securities or other contracts to issue common stock are exercised, vested or converted into common stock unless they are anti-dilutive.
A reconciliation of the numerators and denominators of basic earnings per share and diluted earnings per share for the three and nine months ended September 30, 2012 and 2011 are shown in the following table (in thousands, except per share data):
